CVE-2015-8661
HIGHFFmpeg < 2.8.3 - Denial of Service via H.264 Slice Header Thread Validation
Title source: llmDescription
The h264_slice_header_init function in libavcodec/h264_slice.c in FFmpeg before 2.8.3 does not validate the relationship between the number of threads and the number of slices, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted H.264 data.
